I think you did the right thing with the voicemail, leave it at that and move on. You can’t fix everyone. Surround yourself with people who are thoughtful and supportive, and be the same for them.
I do think a lot of the people who swung right were not trying to hurt anyone, they were misinformed on purpose by targeted propaganda. But again - you are unlikely to be able to get through to them. I stop helping people when it becomes obvious that the help is not helpful. They may come around, they may not, but you cannot personally do anything to make that happen.
And the nonsense about the world not being ready for a woman president is utter twaddle, there have been plenty of them, just not here. Fucking Margaret Thatcher was elected in 1979! Your aunt is off her rocker.
It’s just so good! And yeah it’s cancelled. Preacher went a full 4 seasons, same as the comics.
